Flailing trying to find out how to open Photos.app (aka MobileSlideShow.app) to a specific asset like the Photo Shuffle lock screen

photos-navigation-url-candidates.txt

Decompiling the binary and looking through the methods `-[PhotosWindowSceneDelegate openRoutingURL:]` 
and `-[PhotosURLNavigationRequest _navigateAllowingRetry:]` uncovers some candidates:

- photos-navigation://asset?uuid={uuid}
- photos-navigation://album?name=recents&revealassetuuid={uuid}
- photos-navigation://contentmode?id=photos&assetuuid={uuid}&oneUp=1

Opening up an album by name works but so far I've had no luck figuring out how to show a specific asset.
And ideally it would open up in the photo library tab not the albums tab, just like the Photo Shuffle
lock screen.

An interesting tidbit I learned along the way is that there are a handful of well-known named albums and
those are the only identifiers allowed for the name parameter:

- photo-library
- recents a.k.a. camera-roll
- recently-deleted
- ... and some others I don't care about related to imports and such

And some other hosts / actions that seem to be supported:

- oneyearago
- memories
- people

It looks like these are supported for the photos:// URL scheme as well but I had zero luck opening that
URL at all, rather than the photos-navigation:// scheme which at least opens the app in all cases.

Next step might be trying to figure out which app/framework handles the Photo Shuffle lock screen and
then decompile that to figure out which URL it calls.
